22lr Bolt Weight Gen 3 Adjustable BoreBuddy


Available on back-order


Patent Pending

Our 22lr AR bolt weight system reduces bolt velocity, delaying case ejection and reducing the volume of gas and powder residue released from the ejection port, while eliminating the infamous 22lr AR bolt bounce. The bolt weight engages our bolt buffer at the rear of the BCG, further reducing noise and harshness for a truly refined and reliable system. With a weight, your rifle stays much cleaner, as well.

Gen 3 is here! The adjustable bolt weight allows the bolt weight to be tuned from 6.2oz to 7.6oz (similar to tuning using H1, H2, or H3 configurations in a standard centerfire AR).

Please note: There are a lot of variables in cycling of the AR22 platform, with ammunition selection being the largest of those variables. Significantly reduced power ammunition (CCI quiet, etc.) is generally not recommended and tuning the system for reliable cycling with your particular load may be required. An adjustable weight is recommended for use with the widest range of ammo, from subsonic ammunition through hyper velocity. The heavy duty weight is the “all around” choice and is designed around using bulk pack high velocity ammo.

For reference, the Ruger 10/22 bolt is 6.2oz and Marlin Model 60 bolt is 5.9 oz

The weights are designed to fit dedicated rifles and conversion kits with a Atchisson/Ciener/CMMG/Spikes style bolt.

WARNING: DO NOT use the weight with early production bolts with a rectangular/flat firing pin. Please click here for details

CNC machined from solid stainless steel with tungsten, steel, and aluminum inserts for precise tuning for each rifle and load combination, in the same manner as centerfire H1/H2/H3 buffers. (Adds 1.3oz to 2.8oz)
